ption, but such is not the case. An increasein the percentage of submergence, in the case of a pump offixed length, results in a greater depth of submergence of theair inlet and consequently in an increased air pressure. Witha constant consumption of free air the work input varies withthe… … Fig. 28.—Relation of Efficiency to Input with Constant Length of Pump.Runs (87-202) Series 1. Efficiency and Input.—The efficiencies computed from runs(1—202) of the first series of experiments have been plottedas ordinates against the corresponding inputs in Figs. 27 and28. In order to avoid…
